Abstract
A method for making a threaded bushing in a hollow profile includes providing a hollow profile, and friction drilling the hollow profile using a friction drilling tool. The friction drilling tool is pressed against a first wall that extends substantially orthogonal to a longitudinal direction of the drilling tool and thereby melts through and deforms said first wall and after passing through the first wall contacts and thereby melts and deforms at least two second walls of the hollow profile that extend substantially orthogonal with respect to said the first wall and thereby substantially parallel to said longitudinal direction of the friction drilling tool, such that a substantially cylindrical shaped bushing is formed in the hollow profile. The method further includes screw thread tapping the substantially cylindrical shaped bushing using a thread tapping tool, thereby obtaining the at least one threaded bushing.
